I have a 2015 Sonata 2.0T and I have noticed knocking noise when driving. I experience it more when on the highway/freeway. I mainly experience it during acceleration. Not hard acceleration but when I want to overtake or when the road curves and coming out of the curve -I step in the gas a bit, I hear the knock.
View 11 RepliesIt's a 2006 hyundai sonata LX.
Now Is it anything I should worry about? Car has 72000 on it. Always used synthetic Mobil 1 5w 30.
This is on a completely cold start up, 30 degrees outside. Only makes the noise until car warms up. Anything I can do to prevent this? Or is it not something to worry about? Should I just let the car warm up a little before I drive it?

On the freeway tonight the engine was felt like it was losing considerable power. When I pressed the gas it wouldn't push you into the seat like usual and it shuddered a little. As I was pushing the gas the engine light came on for a couple seconds then turned off. After I exited the freeway, I tried pushing the gas and it wouldn't accelerate. It also seemed like it was limiting itself to 60mph and 4-5k rpm, even when the gas was fully down (not past gate though, I was afraid I wouldn't be able to make it home if I did so). I stopped and turned the car off and on again and the problems seemed to have disappeared. Acceleration came back, car went over 60 and I was able to get it a little past red line with gas pedal past gate.
View 3 RepliesI have a 2007 volkswagen passat 2.0 L...115000 miles. Yesterday I was entering the freeway and I accelerated the car a bit when I started hearing this noise on the engine. I will try my best and describe the noise as a knocking of metal on metal. I thought maybe is the oil and changed it.
Now today I was going up the hill and accelerated the car when the noise appeared again, it happened again a little bit later, again going up a hill. There is no noise when I drive normally or I accelerate and I am not going up a hill.
Experiencing a metallic click or something alike when coming to a full stop?
I've notice this new noise and it seems to happen about 0.5 seconds after the car has come to a complete stop, not during the stopping. It only happens when stopping at a red light, and it doesn't do it on stop and go traffic.
It also doesn't seem to coincide precisely with applying the brakes because is AFTER the car has stopped, again, in less than a second. I hope that makes any sense.
It happens maybe 25% of the time but, then again, if I go to the dealership I'll probably won't be able to reproduce it.
2016 LTD Ultimate, 2700 miles. First and only Hyundai for the moment.
I've experience this one twice, a few weeks apart: cold start the car, and in the first 100 yards or so I'll hear a tapping noise that's clearly rotational, varies with speed but eventually ceases. Sounds like it's coming from front passenger wheel well area, and sounds like a stick or some sort of debris is stuck in the wheel. Both times I've inspected the area and found nothing whatsoever.
I live in an apartment complex area, park in a lot always in reverse so I'm always going from park to drive. The area I live in is wooded ("Pine Barrens" region of Long Island) but the roads are paved so it's not like I'm driving thru wilderness.
I bought a pre-owned 2015 Sonata Limited in November. I only had less than two weeks before the car hesitated upon acceleration and the check engine light came on. At the time, I thought it was a loose gas cap as I'd just gassed up. I took it to the dealership, they pulled the code and it said to replace the accelerator pedal. That required a second trip to the dealership 2 weeks later when they completed the work. Two weeks later and the light came back on. I took it back and asked them to keep it until they found and fixed the root cause while I took a loaner. They kept the car about 2 weeks and when I picked it up, I found that no work had been completed. Two days (!!) later the light came back on.
View 11 RepliesI'm on my second '15 Limited Turbo. Only have 2k miles, but I've noticed an issue with acceleration. When under hard acceleration, especially in 3rd or 4th gear, around 5k RPM the engine starts hesitating. It feels like it runs out of steam. This feeling lasts through beginning of next gear, then the car picks up again. It is actually faster when applying less throttle.
What it could be? It did it since new, I took it to the dealer once, but got some stupid response that it was just rev limiter kicking in (at 5k, right), unfortunately had no time to leave it with them again/show it to them. I also thought it might just go away on it's own, plus I don't usually drive it that hard anyway...
I've noticed distinct engine knocking noise under acceleration/load especially at lower RPMs on a '14 TSI. I'm at 20k miles and wondering if cheap gas from ARCO is the culprit.
View 3 RepliesFew days ago I noticed the noise coming from the engine.
Went to dealership. They removed the oil pan and found metal shavings there .The car has 90,000 miles. They will put a new short block (will be covered by warranty ).
Since they basicaly will disassemble the whole engine, I thought to ask them to replace also drive belts, timing chain tensioner, not sure if the short block comes with the water pump , will ask them . W
I have a 2006 Sonata GL, 2.4L, manual transmission, with about 130K miles. It has recently developed a knocking noise. The noise sounds metallic.
Some data: timing chain, guides, tensioner are all new, the noise is not coming from there.
Compression tests on the 4 cylinders came back with 200, 200, 180, and 200 psi readings. Tests were performed 3 different times, same gauge, all numbers came back the same.
The noise comes on only under acceleration (gas is supplied), and even then it's not consistent. For example, accelerating at 2500 rpm will make the noise, but the noise will go away at, say, 3000 rpm, while accelerating. Then again, the same thing can happen at 3200 rpm: accelerating will cause the noise, but up to a point, beyond which the noise goes away.The noise is not present at idle. I can always make the noise heard, just not consistently at the same rpm range.
I ran the engine with one spark plug disconnected at a time: the noise goes away when the #3 cylinder spark is disconnected.
Opinions vary: wrist pin, piston slap, rod bearing, etc.
Any tests I could run to narrow the problem? It has been difficult to pinpoint where the noise is coming from with a stethoscope...
Oil changes have been very regular (3.5K), using Mobil 1. Nevertheless, it has been burning oil.
My 2009 Sonata 2.4l Sonata has been making a loud knocking noise when it is cold, but it will fade to almost nothing after it warms up. I tried to make a sound clip of the noise, but it was so distorted that I could not even make out the noise on the video.
For some strange reason the noise matches the skipping problem I have been complaining about since the beginning. Yea it's still there. It sounds like it is in the valve system, not the lower end. It leads me to believe it's coming from the valve clearance/ camshaft area.
Rattling noise in the belt area of the engine...
View 3 RepliesI have a 2011 Sonata GLS with 127k miles on it and I'm trying to diagnose a problem, possibly with transmission.
Since I bought the car at 115k miles I started hearing a noise from engine zone, which appears quite rarely. Noise resembles valve knocking, appears mostly at traffic lights and colder weather (evenings). I was trying to catch the sound by recording it while using emergency brake at D pos. but the sound disappeared right after releasing brake pedal.
Describing in a different way it sounds like a propeller touching something with its blades. The sound also appears at 1900rpm on any gear (mostly when slightly releasing gas pedal around 2k rpm).
While trying to understand/fix the issue I used:
- liqui moly valve cleaner and engine flush
- techtron injection cleaner
- replaced spark plugs
These operations had almost 0 effect on car behavior. The symptoms boil down to a torque converter. Transmission shifts fine, I was going to try transmission fluid change ( a full change by dealer), however it may do more harm, so I'm not sure yet.
I have a 2015 Sonata SE 2.4L with 15k miles. Sometimes when accelerating, and almost always when accelerating uphill, the vehicle makes a noise that I can best describe as sounding like a grumbling or rattle from the engine. It almost has a "diesel engine" sound to it. I have noticed this going back to when the vehicle was brand new, but I have recently noticed it more.
View 11 RepliesI have a 2010 Sonata V6 that I bought new. It has a little less than 50K on it. I tried to start it today and it made a terrible noise then died seconds later. I popped the hood and then started it again and the engine was shaking violently in the engine compartment and making a terrible knocking noise. I had driven it 12 hours earlier and it ran fine. I called a tow truck and had it taken to the dealer but if I know my dealer, since it is Sunday they probably wont get to it until Tuesday. Also, this car has had the signature V6 valve cover leak that has been fixed 3 times. I noticed it was leaking again about a month ago and I have just been checking the oil and adding it as it needs it. I dont think the engine ran out of oil because I checked it before the tow truck came and it was between low and full.
View 2 RepliesI have been little irritated with my noisy/rattling sound ride coming from passenger dash, my steering wheel area and some time front passenger belt. I have taken it to dealership and they could not hear anything so they duplicate the problem and no cation was taken. But they found out passenger side ball joint was loose , so they replaced that under warranty.
I wanna know if everyone sonata makes that noise when you go over little bumps on road, rail track crossing ? it just irritates me too much,,how ever the rattle/noise is not much, i cant hear if i have music on.
Yesterday I tapped on passenger side dash and there was a after tapping noise, like vibration. I don't know if its loose plastic or what. I am not able to detect the exact location where the noise coming from. but i am sure one noise is coming from steering wheel on every tiny bumps.
I want to fix it by myself now, cause sometimes noise is there and sometime not. Is there any way to detect the noise ? Noise- more like plastic noise, like loose plastic, hinges squeaking sound, rattling sound.
I am a proud and recent owner of a 2015 Sonata Sport 2.0T!
Car looks amazing and am very happy with it.
But lately I have been noticing lots of drone noise coming from the engine, and a really loud cold start as well. The "cold start loudness" goes away after a little bit of driving.
Was wondering if this is just the way the 2.0T sounds, or should i get it checked?
Been driving my Sonata 2015 2.0t for about 14 months, now. Just turned 13.5k miles. I had first noticed this issue a few months into having the car, but didn't think anything of it. At the time, I wasn't spending much time in the upper end of the rev range. Today, I finally decided that it bugs me enough to investigate.
At WOT, starting around 5500 rpm and going until redline, there is a "raspy" sound coming from the motor that I think might be predetonation, but I'm not sure. It isn't very loud, which is why I originally ignored it, but it is easily noticeable inside the car. I've made some modifications in the past few weeks (Intake, OCC, and Exhaust) so I'm starting to have a bit more fun with the car and want to make sure I get this resolved before it becomes a bigger issue.
Out of curiosity, I looked inside the catch can and noticed a couple drops of fluid (lighter in color), which was surprising since I only installed it ~50 miles ago. Any by "a couple drops" I mean maybe 3mL of fluid. Not sure if that is significant in this case, but I figured it is worth mentioning.
I'm wondering if it could just be the altitude (Denver, CO) and the stock tune is off just a bit? I've been looking into the Lap3 Uncle Chip and HKS performance plugs, but am hesitant to go any further without better understanding what might be happening.
I have been having a grinding/metallic sound when going up hills in 4th/5th gear. It sounds like if you threw metal into moving parts. I believe it's coming from my engine or transmission. When i was at the dealer last month for a campaign and ecm upgrade i mentioned this problem and they replaced the vcm motor assy, however the problem still exists. What could be causing this problem?
View 3 RepliesNew Sonata owner. Got myself a 2015 Ultimate. Is there much difference in acceleration between "Sports Mode", and just running the car in manual mode (shiftronic)?
I know my Elantra used to have a huge acceleration bonus if I ran it in manual mode. Not sure if that caries true here.
